Substitute Part Grouping Explanation

Substitute parts for the UPW1E331MPD6TA are classified into two categories based on the following substitution criteria:

Parametric Equivalent: UPW1E331MPD6TD maintains identical electrical specifications (330 µF, 25 V, ±20% tolerance, 3000 Hrs @ 105°C) and mechanical dimensions (0.315" diameter, 0.650" height, 0.138" lead spacing). This part differs only in packaging format (Cut Tape) and represents a direct functional replacement within the same Nichicon UPW series.

Upgraded Substitutes: ELXZ250EC3331MH15D and ELXZ250ETC331MH15D are manufactured by Chemi-Con and share identical core electrical parameters (330 µF, 25 V, ±20% tolerance, 3000 Hrs @ 105°C) and mechanical compatibility (same case dimensions and lead spacing). These parts are classified as Active products with AEC-Q200 automotive qualification, offering enhanced product status and extended ripple current performance at high frequency (730 mA @ 100 kHz).

Engineering Selection Recommendations

For Direct Replacement (Same Series): UPW1E331MPD6TD provides identical electrical performance and mechanical fit as the original UPW1E331MPD6TA. Both parts carry Not For New Designs status and are suitable for maintenance, repair, or stock replenishment of existing designs.

For New Designs or Long-Term Availability: ELXZ250EC3331MH15D and ELXZ250ETC331MH15D are recommended. Both parts are classified as Active products with AEC-Q200 automotive qualification, ensuring continued manufacturer support and supply chain stability. These Chemi-Con alternatives maintain full electrical and mechanical compatibility while offering enhanced ripple current performance at high frequency (730 mA @ 100 kHz versus unspecified performance in the original part).

All substitute parts maintain ROHS3 compliance and identical case dimensions, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can UPW1E331MPD6TD be used as a direct replacement for UPW1E331MPD6TA?

A: Yes. Both parts are Nichicon UPW series capacitors with identical electrical specifications (330 µF, 25 V, ±20% tolerance, 3000 Hrs @ 105°C) and mechanical dimensions (0.315" diameter, 0.650" height, 0.138" lead spacing). The only difference is packaging format (Cut Tape versus Tape & Reel).

Q: What is the advantage of using Chemi-Con ELXZ250 series parts?

A: The ELXZ250EC3331MH15D and ELXZ250ETC331MH15D are Active products with AEC-Q200 automotive qualification, providing enhanced product status and extended manufacturer support. Both parts deliver superior ripple current performance at high frequency (730 mA @ 100 kHz) compared to the original part's low-frequency specification (474.5 mA @ 120 Hz).

Q: Are all substitute parts mechanically compatible with the original PCB layout?

A: Yes. All substitute parts share identical case dimensions (0.315" diameter, 0.650" height) and lead spacing (0.138" / 4.60 mm), ensuring direct PCB compatibility without layout modifications.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All parts listed are ROHS3 compliant and REACH unaffected. The Chemi-Con alternatives additionally carry AEC-Q200 automotive qualification.

Q: What is the difference between ELXZ250EC3331MH15D and ELXZ250ETC331MH15D?

A: Both parts are electrically and mechanically identical with the same specifications, capacitance, voltage rating, and performance characteristics. The difference lies in packaging designation (EC versus ETC variant codes).
